It is a scout...probably NOT stock, which explains the length. IH was split in 86... Part went to tenneco/Case to become Case IH tractors, who stil is in business and is where the IH logo and trademarks went, and the truck divison went to Navistar, who still makes International trucks. They got the rights to most IH non ag engines. A SBIH is generally larger than a BBF/BBC, from my experiences. They are low speed torque monster engines.
2wd was availiable. Body rot was an issue in salt areas.
I am a fan of the old Loastars, and I would like to try to do a CTD 5.9 swap in one at some point.
